readpass.c patch

[John Dunlap]

To make readpass.c work on first try with gnome-askpass on RHL 7.1:

wget http://bass.directhit.com/openssh_snap/openssh-SNAP-20011023.tar.gz
tar xfz openssh-SNAP-20011023.tar.gz
cd openssh
./configure --with-pam --enable-gnome-askpass --with-tcp-wrappers
mv readpass.c readpass.c1

new readpass.c according to patch I received from djm 5-13-01:
